Big Idea: Many important practical and mathematical applications involve comparing quantities of one kind or another; it is important to know which method to use and how we should use them.
Investigation 4: Comparing by Finding Rates Essential Question: What methods are there for comparing things? Write an equation relating the cost (c) and the number of beads (x) for each type of bead. Spheres: c=.6cents/1x Cubes: c=.8cents/x Cylinders: c=.8 cents/x
